Researchers from the University of Leeds challenged the present medical practice that all heart attack patients should be on beta blockers. The research team revealed that many patients given beta blockers after a heart attack may not be benefitted by being on the medications, recommending they might be overprescribed.

According to Science Daily, the scientists looked at the patients who had a heart attack, however, did not endure heart failure - a complexity of a heart attack where the heart muscle is harmed and stops to work legitimately. The results showed that those heart attack patients, who did not have heart failures, were no more alive after being given beta blockers.

But around 95 percent of the heart attack patients falling in the same category ended up on medications. Beta blockers are an effective gathering of medicines which diminish the movement of the heart and lowers blood pressure. They are regularly endorsed after a heart attack, yet they can have undesirable reactions for a few patients, for example, dizziness and tiredness.

The Guardian reported that the UK medical guidelines recommend that all the patients who have undergone the issue of heart attack should be put on beta blockers, but the new study suggests that this might not be helpful for the patients. The research study has been published in the journal of the American College of Cardiology.

The study involved the analysis of data from the UK's national heart attack register containing a record of heart attack patients who were hospitalized in recent years. Scientists considered the data of 179, 810 patients who were hospitalized for the year 2007 and 2013. These patients had a heart attack but did not suffer from heart failure.

The scientists found no measurable contrast in death rates inside a time of the patients enduring their heart attack between the individuals who had been recommended beta blockers and the individuals who had not. It could mean the medications, which can have reactions for a few patients, for example, dizziness and tiredness, are being overprescribed and burdening patients and the NHS with superfluous medicine costs.
